Over the past two years, the Physics department has been supporting high school physics education with a set of challenging quantum experiments. School classes can visit Leiden University to learn about quantum mechanics, in preparation for their final exams. As of early 2018, this lab has evolved into…

Our object is to identify and characterize transcription factors involved in lignocellulosic biomass degradation in the filamentous fungus Aspergillus niger.

Optical detection of a single electron using a single molecule has never been done. Leiden physicist Michel Orrit and his team have now identified a molecule that is sensitive enough to detect an electron at a distance of hundreds of nanometers. The results are published as a cover article in ChemPh…

Our banking, DigiD and sensitive medical data: what if our entire digital infrastructure can no longer be trusted? Jelle Don has this question permanently in mind as he goes about his research. And that is no bad thing because without new digital security measures, our society will be extremely vuln…

Former PhD, Bachelor and Master students of the Van Exter Lab

During the Bachelor Honours Class ‘The world is quantum’, students from various disciplines learned about the rules of nature on the smallest scale: quantum mechanics. What opportunities and dangers do they see for their field of study?

Actinobacteria are Gram-positive bacteria that have a complex multicellular life cycle and are well known for their ability to produce a wide range of bioactive natural products (NPs).

Petr Steindl works on quantum dots in microcavities for his PhD research. He manipulates single-photons to create complex structures of light. Applications could include quantum communication and gates for quantum computers.

We investigate how radiation pressure can be used to influence the mechanical motion of a micro-mirror suspended from springs.

The quantum computer is on its way, but is society ready for it? Quantum computers have a reputation of being difficult to grasp because of their complexity. This limits society’s ability to envision future applications creating a gap between society and quantum computers. A consortium of 14 knowledge…

A suitcase as a messenger of quantum science. That is the idea behind QuanTour, a project connecting researchers from 12 European universities. In December, the suitcase landed in Leiden. A month later, it is time to pass the baton to Copenhagen. But what happened to it in Leiden?

Koen Bastiaans and his colleagues discovered a new quantum liquid unlike anything ever seen. They did it by using a technique that can be compared to listening to the sound of raindrops falling on a roof. Publication in Science 29 October.

An international collaboration, including Leiden physicist and computer scientist Vedran Dunjko, showed that quantum technology can speed-up the learning process of artificial intelligence (AI). To prove this, the physicists and computer scientists used a quantum processor for single photons. Their…

Quantum Delta NL, a research programme in which Leiden University participates, has been awarded 615 million euros from the National Growth Fund to help develop the Netherlands into a top player in quantum technology. This has been announced at the presentation of the honoured proposals in The Hague…

This is the physics summer school of Leiden University. It is part of the Leiden Institute of Physics (LION). The summer school is intended for Bachelor (BSc) students in physics. It covers topics from quantum matter and optics, to biological & soft matter physics and cosmology and theoretical physics.…

Leiden University organizes a course on quantum mechanics for high school Physics teachers. As the curriculum gains a new quantum component, the university enables teachers to give the best possible guidance to their students.

Besides physics, the sleep of PhD students also benefits from Vitaly Fedoseev's PhD research. He will receive his doctorate on July 7 for his work on optomechanics within quantum mechanics. And also on a setup that eliminated the need for PhD students to push a button every hour for 72 hours.

The high prevalence of pure red cell aplasia in Thailand has been associated with the sharp increase in number of recombinant human erythropoietin (rhEPO) copy products, based on a classical generic regulatory pathway, which have entered the market.

The Physics and Quantum Matter and Optics specialisation is one of the two programmes Leiden offers in experimental physics. The programme can be tailored to individual needs and interests.

The idea of citizens and public professionals collaborating to provide public services has widely spread in several countries around the globe. Co-production is often presented as the go-to solution for challenges like a legitimacy crisis of both the government and the market, and financial concerns.…

The programme guarantees a thorough experience on the frontline of physics research with a practical training of communicative and computer skills.

Filamentous Actinobacteria, such as Streptomyces, produce a plethora of chemically diverse bioactive metabolites that have found applications across medicine, agriculture and biotechnology.

Telling sensationalised stories, exaggerating benefits and understating the risks: creating ‘hype’ about something doesn't sound like something a responsible scientist would indulge in. Or could we also use hype in a ‘good way'? What could we achieve by opening up quantum futures for wider discussions,…

Light can be used to apply forces on single cells. Focused lasers have been used by physicists to tweeze particles and to manipulate them. These so called “optical tweezers” can be used as mechanical phenotyping tools for characterising the mechanics of materials and living objects.

Streptomyces bacteria are a valuable source of natural products, many of which are used in the clinic or in biotechnology.

Turkic nomadic rulers established large empires in the Middle East and Asia between the 11th and 14th centuries. This project will explore the link between their political ideology and the production of art and literature, via the cultural heritage of five cities along the Silk Road: Kashgar, Samarkand,…

‘Quantum technology is going to change the world, but most people don’t feel connected to it. I want to change that,’ says Julia Cramer, assistant professor at Leiden University. Known for her passion for science communication, Cramer actively seeks opportunities to share the wonders of quantum technology…

The van Exter group has an extensive history of prior research in classical and quantum optics. As former part of the group of Han Woerdman, we have studied topics as diverse as:

This dissertation is concerned with the study of the less than twenty remaining precolonial Mesoamerican codices. By considering these rare and fragile pictographic and hieroglyphic books from the cultural biography perspective, many different aspects of these books can be studied.
